This study provides quantitative evidence on how the use of journal rankings
can disadvantage interdisciplinary research in research evaluations. Using
publication and citation data, it compares the degree of interdisciplinarity
and the research performance of a number of Innovation Studies units with that
of leading Business & Management schools in the UK. On the basis of various
mappings and metrics, this study shows that: (i) Innovation Studies units are
consistently more interdisciplinary in their research than Business &
Management schools; (ii) the top journals in the Association of Business
Schools' rankings span a less diverse set of disciplines than lower-ranked
journals; (iii) this results in a more favourable assessment of the performance
of Business & Management schools, which are more disciplinary-focused. This
citation-based analysis challenges the journal ranking-based assessment. In
short, the investigation illustrates how ostensibly 'excellence-based' journal
rankings exhibit a systematic bias in favour of mono-disciplinary research. The
paper concludes with a discussion of implications of these phenomena, in
particular how the bias is likely to affect negatively the evaluation and
associated financial resourcing of interdisciplinary research organisations,
and may result in researchers becoming more compliant with disciplinary
authority over time.Comment: 41 pages, 10 figure
